The use of hybrid organic-inorganic materials in gas separation is a topic of great interest. One recent example is the observed increase in separation performance of polymers upon confinement in a mesoporous medium [M. Moaddeb, W.J. Koros, Journal of Membrane Science 125 (1997) 143-163].

## Abstract A procedure is presented for determining the concentration of polymer lithium, alkyllithium, and monomer by use of small‐molecule GPC. The system poly(styryllithium), butyllithium, styrene, and benzene are used to illustrate the method. The method as presented has a lower limit on the d

Pressure-composition isotherms were determined at 20ЊC for CO 2 in Kapton and various substituted polycarbonates and for H 2 O, Ar, N 2 , CH 4 , and acetone in bisphenol-A-polycarbonate. The isotherms are described by two parameters an average free energy of sorption and a width of a Gaussian distri

The accurate measurement of water vapor sorption and permeation in polymers is complicated because water has a tendency to adsorb on high energy surfaces, a relatively high heat of vaporization, and a high solubility in most polymers. These issues and the difficulties they cause in the design of sor
